To aZZ whm it may concern:

Be it known that I, Omv R A. HnLMEn, a

subject of the King of Gr at Britain, and

resident of the borough of Manhattan, city,

county, and State of New York, have invented certazin new and useful Im' rovements in File-Records and Mounts for -Ray Negatives, of which the following is a speci fication.

In the treatment of teeth it is frequently necessary to make an X-ray picture so that a proper diagnosis and location of the trouble can be made. The X-ray negative film when finished is examined carefully and the proper treatment determined upon. These X-ray negatives are desirably placed in a suitable holder in order that they may be picture record of the case.

viewed properly and the holder is desirably formed as a filing card so that a complete record of the case including the X-ray negatives may be put in a suitable filing cabinet and maintained as a convenient permanent It is the main object of this invention to provide a simplified and improved filing card and mount adapted to receive one or more negative films, the filing card and mount being in such form that the negative or negatives therein-will be completely protected on both sides and securely 'held to prevent accidental detachment.

A further object of this invention is to provide a mount of opaque material-having openings therein covered by flexible transparent or translucent material, means being provided around the margins of each openlng to securely hold a negatlve film 1n contact with the said flexible material. 7

Another object of the invention is to pro vide an opaque-flap for the card or mount which will protect the negative when folded close to the body of'the mount,- and which may also be usedas a shade for the negatives .when the card or mount is held up to the light for an examination of the negatives.

Another object of the invention 1s to pro-' vide an opaque mount or card having an opening therein and to secure a cross set opening and sheet of transparent or translucent gelatin.

Another object of the inventionis to provide 'an X-ray negative mount and a gelatin sheet of opal color.

In the accompanying drawings:

.Figure -1 is a face view of a mount constructed in accordance with this invention,

a portion of the structure being broken away to more clearly show its construction;

Fig. 2 a vertical sectional view on the line II-II of Fig. 1; v

I Fig. 3 a horizontal sectional view on line IIIIII of Fig. 1; and

Fig. 4 a view similar to Fig. 1 showing the mount adapted to receive a single large negative, a portion of the structure being broken away to more clearly show its conv struction.

Referring to the various parts by numerals, 1 designates an opaque sheet, preferably of paper, which is folded at 2 to form an inner body member 3, said inner body member being equal in area to the main exterior body member l of the mount. Both the inner and exterior body portions are cutout to form registering openings 5, said 0 enings being slightly smaller than the -ray negatives to be supported in the mount. Between the inner and outer body members is placed a sheet 12 of flexible transparent or translucent material, prefer-' ably gelatin, and this sheet and the two body members are connected together by rows of stitches 6 of thread or wire which pass along the upper and lower edges of the body members and vertically between the openings, and also parallel with the side edges thereof. A center line of stitches 7 also secures the two members and the gelatin sheet together ,lower row of openings. These slits provide openings through which the X-ray negative films may be inserted into the pockets formed by the rows of stitches as shown clearly in Fig. 2. In that View 10 designates the mega 1 tive filmsin position in the pockets. Thev gelatin ,slieet is preferably smooth'on both sides {and ofa clear opal color. I have found that by the 'use of an opal colored elatin sheet Lam enabled to get a proper illumination of the X-ray negative while at the same time eliminating all objects beyond thenegative. The opal gelatin sheet permits the passage of light rays to the negative but is not sufiiciently transparent to permit objects to be seen through it. I prefer to-use a gelatin sheet which issmooth on its inner side and. to so insert the negatives in the pockets that the image side of the negative will be a ainst the smooth side.

of the gelatin sheet. 11 this'way all danger of scratching or marking the image on the vne ative is avoided.

prefer to use an opaque card in order to concentrate the light on the negative and to cut out all surrounding images which might V edge of the body of the mount. This flap is preferably formed integral with the outer 100 y member i, as shown clearly in Fig. 2. This flap serves as a. protecting cover for the mount when it is filed away and also serves as a light shield at thetop of the mount when viewing the negatives. This is a great advantage as each mount is provided with a ermanently attached or integral light shleld which when arranged as shown in Fig. 2, efl'ectually cuts out all light rags from the top, with a result that a very cient illumination of the negatives by light rays passing through the openings in the exterior body member of the mount is secured.

On the face of .the inner body member may be printed suitable headings or indications to receive information as to the patient and-- case.

The mount shown in Fig. 1 is provided with an upper and lower series of negative receiving pockets and correspondirw wind ows or openings, the upper series bemg designed to receive pictures or negatives of teeth in the upper jaw and the lower series of openings being. designed to receive pictu'res or negatives of teeth in thelower jaw.

The mount is also designed and labeled in .such a manner that the pictures of teeth in the upper left jaw will be placed in the upper leftside of the mount. The pictures 9 the teeth in the upper right side of the aw may be placed in the upper right side of the mount. Thepictures of the teeth-in the lower jaw may be similarly arran d in the lower series of-openings while til; incisors or front teeth pictures will be arranged inthe center of the mouth, either in the u per or the lower row, as the case may be. y this means the pictures of the teet will be arranged in the mount substantially.

as the teeth are in the mouth of the patient.

This assists the dentist or operator in fixin in his mind the location of the disease teeth and also enables him to at once find the picture of the tooth that he is treating or considering.

In Fig. 4 the inner member of the body of the mount is designated by the reference character 3, the flap 9, the slot to receive the negative 8, the 'gelatinsheet 12, and the lines of stitches 6". The ne ative film in this view is designated by t e character 10*.

What I claim is:

1. A- mount for X-ray negative films, comprising an outer body member and an inner body member of opaque material and formed with registering openings, a sheet of flexible material between said body members and bridging the said openings said flexible material permitting the passage of light rays therethrough, .and lines of stitches connecting the body members and the flexible sheet together and forming a pocket around the openings, the inner body member being slit to form an opening into said pocket and to permit the X-ray negative film to be placed in the pocket and against the inner side of the flexible sheet.

2. A mount for X-ray negatives comprising an outer body member and an inner body member of opaque material and formed with registering openings, a sheet of flexible material between said body members and bridging the openings said flexible material permittlng the passage of light rays therethrough, lines of stitches connecting the body members and the flexible sheet together and forming a pocket around the openings, the inner body member being slit to form an o ening into said pocket and to permit the -ray negative to be placed in the pocket and against the inner side of the flexible sheet, and an opaque flap connected to the upper edge of the body portion of the mount.

3. A mount'for X-ray negatives comprising an outer body member and an inner body member of opaque material and formed with two longitudinal rowsof openings one row being above the other and the openings in one body member registering with the openings in the other body member, a sheet of; flexible material between saidbody members and bridging the openings, said flexible material permitting the passage of light rays therethrough, lines of stitches connecting the body members and the flexible sheet together and forming a pocket around each pair of registering openings, the inner body member being slit above the upper row of openings to form entrances into the upper row of pockets, said inner body member being also slit below the lower row of openings to form entrances into the lower row of pockets, said slits permitting the X-raynegatives to be placed in the pockets against the inner side of the flexible sheet, and a flap of opaque material connected to the upper edge of the body member of the mount and 10 adapted to be folded over to cover the inner side of the mount. 4

In testimony whereof I. hereunto afiix my signature.
